London’s Best Sushi | The Best Restaurants for Nigiri and Sashimi | Eater London

"Chef Yoshinori Ishii trained at one of Japan’s most revered kaiseki restaurants Kitcho, went to become the chef-in-residence of Japanese Embassies in Switzerland and USA, and moved to Umu in 2010. Contrary to the belief that chefs should stay and work hard in their own kitchen, Ishii has been spending time profitably outside Umu, mostly in Cornwall, in order to elevate the ways locally caught fish could be treated — he introduced ike jime practice to Cornish fishermen — and to source directly into his restaurant. On the menu, find many world-class fish caught in the Cornish waters: from mackerel and sardine, to red mullet and turbot, to squid and spiny lobster — as well as extraordinary wild eels from Ireland. Ishii also offers a vast selection of vegetable nigiri, inspired by his own kyo-kaiseki training." - Poonperm Paitayawat
